Battery discharge protection
Vehicle battery state of charge
function
The function guarantees longestvehicle battery life via a generator
with controllable power output and
optimised power distribution.
To prevent discharge of the vehicle
battery when driving, the following
systems are reduced automatically in two stages and finally switched off:
● heated rear window
● heated windscreen
● heated mirrors
● heated seats
● fan
In the second stage, a message
which confirms the activation of the
vehicle battery discharge protection
will be displayed in the Driver
Information Centre.Switching off electric lights
To prevent discharge of the vehicle
battery when the ignition is switched off, some interior lights are switched
off automatically after some time.

Driving and operating151In the event of a fault, control indicator
g illuminates. Additionally, a
warning message is displayed in the
Driver Information Centre. Vehicle
messages 3 104.
Continued driving is restricted or not
possible, depending on the fault.
Have the cause of the fault remedied
by a workshop.Brakes
The brake system comprises two
independent brake circuits.
If a brake circuit fails, the vehicle can
still be braked using the other brake
circuit. However, braking effect is
achieved only when the brake pedal
is depressed firmly. Considerably
more force is needed for this. The
braking distance is extended. Seek the assistance of a workshop before
continuing the journey.
When the engine is not running, the
support of the brake servo unit
disappears once the brake pedal has
been depressed once or twice.
Braking effect is not reduced, but
braking requires significantly greater
force. It is especially important to bear this in mind when being towed.
Control indicator R 3 94.
Antilock brake system
Antilock brake system (ABS)
prevents the wheels from locking.ABS starts to regulate brake pressure as soon as a wheel shows a tendency to lock. The vehicle remains
steerable, even during hard braking.
ABS control is made apparent
through a pulse in the brake pedal
and the noise of the regulation
process.
For optimum braking, keep the brake
pedal fully depressed throughout the
braking process, despite the fact that
the pedal is pulsating. Do not reduce
the pressure on the pedal.
After starting-off the system performs a self-test which may be audible.
Control indicator u 3 94.
Adaptive brake light
During full braking, all three brake
lights flash for the duration of ABS
control.

the actual distance.
Warning symbols
Warning symbols are indicated as
triangles 9 on the picture, which show
obstacles detected by the rear
sensors of the advanced parking
assist.
Additionally 9 appears on the top line
of the Info-Display with the warning to
check the vehicle surrounding.
DeactivationThe camera is deactivated when a
certain forward speed is exceeded or
if reverse gear is not engaged for
approx. ten seconds.
Rear view camera can be manually deactivated in the vehicle
personalisation menu in the
Info-Display. Vehicle personalisation

warning symbols
Activation or deactivation of the visual
guiding lines and the warning
symbols can be changed by touch
buttons in the lower zone of the
display.

Fault messages are displayed with a
9 on the top line of the Info-Display.
The rear view camera may not
operate properly when:
● The surrounding is dark.
● The sun or the beam of headlights is shining directly into
the camera lens.
● Ice, snow, mud, or anything else covers the camera lens. Clean
the lens, rinse it with water, and
wipe it with a soft cloth.
● The vehicle is towing a trailer.
● The vehicle had a rear end accident.
● There are extreme temperature changes.
